'Self-breeding' virus is challenging security software

'Self-breeding' virus is challenging security software - the most widespread virus in 2009, to over 483,000 computers, called W32.SalityVF.PE - belongs to the most "annoying" virus strain today. Super polymorphic viruses are capable of self-breeding . There have been 50,128 new virus strains appearing in Vietnam in the past year, 1.5 times higher than in 2008 and 7 times higher than in 2007. These viruses have infected over 64.7 million computers.

'Self-breeding' virus is challenging security software Picture 1 Super polymorphic viruses are likely to break out in 2010. According to Bkav's metamorphic virus removal system, 2.2 million computers were infected with the virus last year. Viruses W32.Sality.PE and W32.Vetor.PE constantly "dominate" on the statistics table of the most contagious viruses. Super polymorphic viruses have truly become a challenge not only for users but also for anti-virus software.

Super polymorphic virus is the new 'high-end' generation of previous polymorphic strains. Polymorphic viruses have the ability to automatically convert their own code, creating different variations in each infection. In the meantime, common viruses always maintain the same type of code in all infections, in other words, there is only one type of variation. This 'change of shape' ability enables polymorphic viruses to hide subtly from the scanning of anti-virus software.

Super polymorphism is a more "sly" virus, combining many types of overlapping polymorphisms. They use genetic algorithms to automatically breed with each other, producing generations of 'descendants' F1, F2, etc. The longer the infection is on computers, the more polymorphic viruses produce more variations with The higher the complexity, the more difficult it is to identify and remove class of antivirus software. Therefore, the current super polymorphic viruses can overcome all the most famous antivirus software in the world.

Regarding the level of vandalism, the polymorphic virus is even more dangerous than other viruses. They cause serious problems with the system, which can lead to data destruction, reducing the security level of the system.

As predicted, in 2010, the virus will continue to appear every day in increasing numbers, especially dangerous viruses such as polymorphic viruses. With the ability to constantly create complex variations, the risk of a "pandemic" virus of a metamorphic virus is entirely possible. Non-alert users are only relying on the anti-virus software race.

In addition, the Revised Criminal Law officially came into effect earlier this year will create a legal corridor to criminalize those who spread computer viruses. If previous cases of virus scattering were only administratively sanctioned, then from 2010 this behavior could be criminally prosecuted and imprisoned for 1 to 12 years.
